Employee Hierarchical - Rolling down reporting

[imkoolkrab]

Hi All,

I have employee table with following structure

empid
mgrid
startdate
enddate
other emp details

I have built reporting tool that lets user select date and manager and it will list all employees under that manager. i have used oracle connect by to list all employees reporting to selected manager recursively till last level. It takes too long to list. Is there anyway i can organize data that can help me speed up query?

Thank you in advance.

The general solution is a hierarchy bridge table. Review this thread for more information:

Warren sums it up nicely in the last post.
